Abstract : Airmen Against The Sea is the fourth in a series of ADTIC studies to determine how military personnel survived under meegency conditions in variaous parts of the world. Its predecessors, 999 Survived, Sun, Sand and Survival, and Down In the North, dealt with survival respectively in the Southwest pacific Tropics, in ther African Deserts, and in the Arctic. This study concerns survival at sea dn, like its predecessors, employs the topical approach. It is not a water survival manual, but is a factual report of what happened to men who bailed out or ditched at sea, and whose only refuge for days on end was a rubber lifeaft. Under such topical headings as bailout versus ditching, survival equipment, the lifeaft, food, hazards, injuries, morale, and many others, the experiences of the survivors themselves are emphasized. The result is a new and fresh insight into the problems of survival at sea which will eb of inteest to all those wh ofly over water, and of particular value to those concerned directly with rescue operations, with water survival training, and with the development of survival materiel.
